Help! Just got my TS-Optics 90mm CF APO, and I am getting these odd artifacts on my images. 

 

Camera asi2600mm pro, chroma LRGB filter set, comes up on all filters but if move the camera to a certain point in the sky they go away. Seems like a light leak would be the issue.

Looks like a bright star just outside the field reflecting off something.....note the diagonal 'ray' in addition to the well defined objects.

Does this seem right for a filter like the chromas? Just got the 36mm LRGB set from them

At least you figured out the source of the problem fast!

Yes I am lucky I did. 

 

Actually what I did was shut all lights off and had a pitch black basement. Then I traced the scope and filter wheel with a flashlight till I found the source while looking down the scope. Very odd! but it is a new design filter wheel off the older ZWO one I had
